TF and hyperinsulinemic hypoglycemia, familial, 4: When evaluating subsets of other notable gene families, such as transcription factors and specifically the DNA binding domains of TF families involved in plant stress responses, such as AP2, WRKY, NAC, bZIP and B3, the lateral root apex displays a larger number of genes that also exhibit a greater up‐regulation of P deficiency response genes compared with either the seminal root apex and the seminal root sub‐apical regions.
